Tabla Triggered DIY Sequencer Drummachine

Internals of my home made analog sequencer

YouTube via joystickmusic — April 11, 2010 — "This sequencer is triggered by a Riyaz "proffessional" (sic) tabla box."

Drummachine: proof of concept. No proper sounds assigned yet.

"joystickmusic — April 11, 2010 — This proves the machine works how I planned it. I can drum a beat, and the sequencer will store the sounds in the 32 positions of the sequencer. Closing the volume knob erases it. It can't do triplets (yet) as you can tell."

Foes dub: Setting up a sequence and a beat

"joystickmusic — April 16, 2010 — This is not the best Jam. It's too sluggish. But I found it nice to show off how easy it is to set up a sequence on a quantized sequencer and how easy it is to tap a beat."

Chins

"joystickmusic — April 22, 2010 — Same features as yesterday, same sequence, different sounds, different music.
BTW: There's no computer involved while playing this music. There's just the tabla machine, the sequencer and tw joysticks. A Miduino is digesting their data and plays a Waldorf Blofeld."

RS95 VCO Reaktor Emulation

YouTube via t0nmontana — May 10, 2010 — "Just having a bit of fun modulating the symmetry and duty cycle of this here triangle wave."
some additional info via Gregtronic:
"I made a fun little patch in Reaktor that emulates the RS95 or EMS style VCO. Here's a video of me having a little fun modulating the Symmetry and Duty Cycle. It doesn't sound all that great, but it's fun to watch the waves dance!"

Rare 1984 Casio KX-101 boombox keyboard

YouTube via Fingermush — May 05, 2010 —

"This is a very short demo, of a rare Casio boombox. My camera doesn't do this thing justice. The drums & some of the tones are really cool."

"main features:
* 37 mini keys
* 12 key buttons + 11 select buttons for direct selectable single finger chords
* 2 detachable 2-way loudspeaker boxes (with some bass, tweeter is slightly hissy)
* main voice polyphony 4 notes (only 1 in unison mode)
* 9 preset sounds {piano 1..3, harpsichord, organ, clarinet, flute, horn, mellow}
* 12 preset rhythms {waltz, ballad, swing, enka, 16beat, rock-1..3, disco-1..2, bossa nova, samba}

* preset sounds, rhythms & sequencer note lengths selected through keyboard keys
* cipher buttons {'0'..'9', 'set', 'c'} (only used by tape deck?)
* main volume slider
* treble & stereo balance sliders
* separate volume sliders for poly (keyboard main voice), mono, chord, arpeggio, rhythm, mixing microphone
* stereo/ mono switch
* tempo +/- buttons (57 steps, most are slow)
* transpose +/- buttons (13 semitone steps)
* arpeggio

* detuned chorus mode (called "unison", monophonic)
* 3 rhythm fill-in buttons
* complex sequencer (473 steps, polyphonic with edit features, saves music files on audio cassette)
* 2 "one key play" buttons (to play or edit sequencer contents note by note)
* semi- analogue sound generator similar like Casio VL-1; the digital envelopes (with audible zipper noise) are linear and thus sounds unrealistic because they fade silent too soon. Unlike the latter it is 4 note polyphonic and alternatingly assigns notes to both stereo channels. Chord voice is 4 note polyphonic with fixed timbre like Casio PT-30 but has an optional arpeggio voice. Analogue percussion corresponds to PT-30.

* very complex multi- chip hardware:
o CPU1= "NEC D1868G 006, 8348XK, Japan" (80 pin SMD)
o CPU2= "NEC D1879G 002, 8343XK, Japan" (80 pin SMD)
o 2x SRAM= "HD C, 61914, 4F, 23" (44 pin SMD)
o tape drive CPU?= "Toshiba TC4514BP, 8418H, Japan" (24 pin DIL)
o IC "LB1405, 4A3" (16 pin DIL)
o tuner IC "441, A04" (16(?) pin DIL)
o big hybrid "K4F25S, 46311"
* radio tuner:
o FM stereo, MW, LW
o analogue scale with tuning knob
o telescope & ferrite antenna
o nice sound
* digital controlled cassette deck:
o "computer play" drive control buttons {space search, rec return, repeat, single, program, shuffle, intro, JP}
o direct title select through cipher buttons
o tape sorts switch {normal, CrO2, metal}
o tape counter (mechanical)
o record mute button (records a pause)
o datasette function to save & load sequencer data
o 2 integrated microphones
o has no dolby, sounds bassless
o fails by hardening rubber parts
* level meter (7 LED row with only 5 steps, mono)
* timer switch (to be used with an external mains timer to play or record)
* RAM-Pack slot (for optional Casio RA-10 module that expands sequencer memory to 985 steps)
* tuning trimmer (+/- 30cent)
* auto- power off (in keyboard mode)
* jacks for mains cable, speakers, line out, phones, line in, microphones, mixing microphone"

Catgirl Synth Burst Generator - MOTM Format

via this auction

"Designed by Ken Stone of Cat Girl Synth.
This module is a rhythm and timing accessory. It generates a burst of gate or trigger pulses at various speeds as set from a front panel control.

At higher speeds it can be used for washboard, maracas or similar rapid-burst percussive effects when connected to the appropriate sound generating device such as a ringing oscillator. At lower speeds it can be used to step a sequencer a certain number of steps or retrigger an envelope shaper. The output pulses are quite narrow when the specified component values are used, and would best be described as trigger pulses in synths that distinguish gates from triggers. Increasing some component values will give longer gate like pulses.

Just a few of the ways in which it could be used; It can be used alone or cascaded with other burst generators. When cascaded, it could form the basis of a weird rhythm/timing generator. It could be used to step your sequencer through so many notes each down-beat. Fed to the modulation input of a VCO either directly or via an envelope shaper, it will cause a trill at the beginning of each note. It can use either its internal synchronized clock, or an external clock. It can be configured to be retriggerable or not, in which case the event in progress is concluded before it will respond to another.

ROLAND MPU-101 MIDI-CV INTERFACE

via this auction

"This unit lets you use an older synth without midi within a midi environment. It converts midi signals into CV input signal for analog synths so that you can use vintage and/or analog synths in your midi setup. This unit can handle up to 4 analog synths. 16 midi channels, Midi In/Out/Thru, Mono/2Voice/3Voice/4Voice/Special. Each of the 4 outputs send CV, Dynamics, and Gate, from midi to 4 synths and then there's also Bender, Modulation, After Touch, and Volume available.
